either a horizontal or a vertical position.

This invention also consists in certain other features ofv Constructionand in the combination and .arrangement of the sevcral parts, to behereinafter fully described, illustrated inthe accompanying drawings andspecifically pointed out-.in the appended claims. .s

In describing my invention in detail, reference will `be had to theaccompanying drawings wherein like characters denote like orcorresponding` parts throughout the several views,sand in which L vFigure 1 is an elevationof the device.

Figure 2 is a plan View.`

Figure 3 is a vertical sectional view through the blade supporting andoperating means. f

p with the ends of the.crank`s.

In these views, 1 indicates a tripodlike fra-ine., the legs of which'aretelescopic so thatrthe frame can be adjusted on uneven ground to maketheV seat 2 at the converging portions of the legs level aswell as thesaw supporting means. The' front leg of the framevis formed with asubstantially rectangular shaped partB which forms a bearing for a crankshaft t, pedals 5 being connected A large gear 6 is fastened to theshaft. These parts are so arranged that a personsitting on the seat 2can place his feet onthe pedal and thus ro-V tate the crank shaft andthe gear by a movement of his feet. An upright frame 7 is formed on thelower end of the front leg of the main frame, and this frame 7 isformed'with a guideway 8 for a rod 9 and with a bearing 10 for a hollowshaftvll which has a pinion 12 at its inner end engaging thek kgear 6. Ashaftr 13 is slidably mounted in the hollow shaft and is keyed theretoso that it must rotate with said hollow shaft 11. This shaft 13 has abeveled pinion 14 on Figure Lis `a section on line l-tof Figitsouter-fend. The rod 9 has its outer end ,bent4 upwardly and .formed'with Ya yoke 9 Ithrough one'V prongV of, which the shaft .13,

passes and rthroughthe other prongof `whichaspindle 15 passes, thespindle being held in :this ,prong` bythe nuts' and washers 16. Thisspindle extends horizontally Vfrom`r a vertically arranged hub A17 whichhas a socket therein which'is arranged diametricallyV opposite thespindle and receives a projection 18, at'the center of the'pinion141:'.V The lower end of a saw shaft 19 is 'journaled in the hub landthe 'upper end of this shaft is Vjournaled in an Varinf20- whichis-rotatablyf supi Y' ported on thebearing 10 of shaft 11. AThe sawblade 22 is fastened to thel shaft'b'y means of the nut and"washer 23which presses theblade against a gear 24 onv the shaft, saidfgear'kmeshing with the gear 14.

"From thel foregoing, it will'be lseen that s and the like,'the nut'16is loosened so that the hub 17 can be given a quarter turn to place thesaw blade in a vertical position. Then the nut is tightened to hold theparts in this position. As kwillbe seen,vthe arm 20 moves with the sawshaft,'its inner part turning on part 10 ofthe frame 7 i The saw bladecan also be moved toward and away from its work through means of thesliding bar 9 and the telescopic shafts 11 and 13; The parts are held inretracted position by the spring 2.5 on the rod 9 and a cable 26 whichis fastened to the rear end of the rod 9 and passes' over the guidingpulleys 27 ,i is provided for movingthe parts for` waidly against theaction of the spring when a handle 28 on the cable is pulled by theoperator. This spring Y is a coiled spring arranged on the rod andhaving one end are provided with ball bearings 31 for reduelli ingfrietion to a minimum.

Thus I have provided an e'l'leetive structure for operating a saw by thefeet of the operator7 the operator sitting down with his hands tree tomove the saw to and from its work. Ott course, if desired, al motor maybe attached to the e `ank shaft so `thatthe saw will be power driven,and the parts may be so arranged that a number of men can sit on theframe and ope-rato crank shafts for driving the saiv, where one manwould be unable to do the Work by himself.

It will, oit` Course, be understood that the saw can beheld atanyintermediate point between the vertical and horizontah if desired.

lt is thought from the foregoing deseription that the advantages andnovel features ot my invention will be. readily apparent.

`l desire it to be understood that I may inake ehauges in theconsti-notion and in the Combination and arrangement of theseveralparts, provided that such ehanges :tall with in the scope ot' theappended claims.

What l claim is 1` A saw1 device eomprising a trame, a tubular shaftjournaled in said frame, a second shaft slidbly and non-rotatablymounted inthe lirst shaft., al beveled gear on the outer end of these'eond shaft, a member slidably mounted in the 'trame and having y ayoke-shaped part through one`1nong ot which the second shaft passes. ahub having a part rotatably engerging` a projecting part on the gear7 aspindle on thehub passing through the other partot' the `yoke7 means forrotatably connecting the spindle with said part Vof the yoke, a` sawarbor rotatably mounted in the hub,`a beveled gear carried thereby andmeshing 1with the first gear, a saw carried by the arbor, meanspermitting the slidable member to be moved to cause its yoke part tomore thesaw outwardly againstthe work and means for rotating the tubularshaft.

2. A Sau' device eomln'ising a trame, a tubular shaft journaled in saidframe, a Second `shat't slidably and` nonrotatably n'iounted in thefirst shaft, a beveled gear on the outer end of the second shaft, amember slidably mounted in the `frame and having a yoke-shaped partthrough one prong of which the second sha't't passes, a hub having apart rotatably engaging a projecting part on the gear, a spindle on thehub passingg`r through the other part of the yoke7 means 'for rotatablyconnecting the spindle with said part of the yoke, a saw arbor rotatablymounted in the hub, a beveled gear earried thereby and meshing with thelirst gear, a saw 'arrezl by the arbor7 means permit# ting the slidablemember to be moved to cause its yoke part to .move the sa7 outwardlyagainst the work, means for rotating the tubular shai'tand an L-shapedarm having a lararing at one end for engaging the part ol" the :trainewhich forme a bearing' for the tubular shaft and itsother endiormingl abearing for the saw arbor.

l. A Haw lleviee comprising a frame provided with legs, a lront uprightextension on the frame having a horizontal `bearing at its upper endanda horizontal guideway below the bearing, a rod slidablv mounted inthe guideway and havingr its outer end bent at rightangles and formed`with a yoke, a spring on the rear part of therod Ytorholding the samein its rearward position yvithone prong ot the yoke engaging the :frontend of the bearing, a tubular shaft rotatably mounted in the bearing, asolid sha'ltslidably and non-rotatably mounted in the tubular shaft,said solid shaft't passingthrough the inner prong of the yoke, a gear onthe outer end ol said solid shaft, a hub rotatably mount ed on aprojection at the center of the gear, a spindle on the. hubrotatablyConnected with the outer prong` of the yoke, a saw arbor journaled inthe hub, a saw carried thereby, a drive shaft mountedin the frame, gearsconnecting the same with the tubular shaft, a. cable eonnecti-al withthe rear end ol" the slidable rod and passing over pulleye on the iframeparts for proj eating the rod when the cable is pulled upon, springlmeans for holding the rod in retracted position and a sea t on theframe,
